Application of Bone Augmentation Techniques in Dental Implant Restoration

Bone augmentation techniques are crucial for addressing bone deficiency in dental implant restoration, significantly improving both initial stability and long-term success rates. Bone insufficiency often results from periodontal disease, trauma, or prolonged tooth loss, which compromises implant stability and osseointegration outcomes. This article systematically examines clinically used bone augmentation methods, analyzing the biological principles, advantages/disadvantages, and current clinical applications of Guided Bone Regeneration (GBR), bone grafting, bone split techniques, and maxillary sinus lift surgery. While autologous bone grafting demonstrates high osteogenic potential but carries significant trauma, bone substitutes offer abundant sources yet face limited efficiency. GBR minimizes trauma but risks membrane exposure. Emerging bone enhancement materials (e.g., -tricalcium phosphate, hydroxyapatite), 3D printing technology, and tissue engineering have substantially improved regenerative efficacy while reducing surgical trauma, though their high costs and limited clinical adoption remain challenges. This study compares the indications and limitations of different bone augmentation techniques, exploring the application prospects of emerging technologies in dental restoration.
